Thailand's Meteorological Department warns of unstable weather through May 10, with heavy rain and strong winds expected across the country, particularly in southern Thailand where downpours could reach 60% coverage tomorrow.
On May 5, 2026, the Thai Meteorological Department forecasted weather conditions for the next 24 hours showing continued thunderstorms and strong gusts in northern Thailand due to a high-pressure system and cold air mass from China covering the northeast and South China Sea, combined with southerly and southeastern winds bringing moisture from the Gulf of Thailand and South China Sea. Residents are warned to avoid open areas, large trees, buildings, and weak structures during thunderstorms and strong winds. Farmers should reinforce fruit trees and prepare to protect crops and livestock from potential damage, while monitoring their health during changing weather conditions.
The southern region will experience increased rainfall with heavy downpours in some areas as an easterly wind stream covers the lower southern region. Residents in the south are cautioned about heavy rain dangers. Sea conditions in the Gulf of Thailand and Andaman Sea show waves around 1 meter high, exceeding 2 meters in thunderstorm areas. Fishermen should exercise extra caution and avoid thunderstorm zones. Northern Thailand currently shows light to moderate dust and haze accumulation due to scattered rainfall.
